Posture has a bigger effect on reflux than most people realize, mainly because slouching or sitting hunched over directly compresses the stomach, increasing pressure against the lower esophageal sphincter.
Why this happens
A slouched, forward-leaning posture — common when sitting at a desk or eating while hunched over a phone — reduces the space available in the abdomen, which pushes stomach contents upward against a muscle that's already working to stay closed. This effect is especially noticeable right after eating, when the stomach is fuller.
Where this shows up most
Eating while slouched at a desk, sitting in a low, reclined car seat right after a meal, or lying on the couch to watch something after dinner are all common posture-related reflux triggers that have nothing to do with the food itself.
Simple posture fixes
Sitting upright while eating, avoiding phone or laptop use hunched over during and right after meals, and standing or walking rather than sitting slouched for the first hour after a meal are low-effort changes that address this specific contributor directly.
